VESPEL®

Description

Vespel® is a sophisticated high performance plastic that performs over a wide range of temperatures and stresses. Parts made from Vespel® provide a unique combination of the physical properties of plastics, metals and ceramics. It performs well with or without lubrication in various applications. Vespel® resists wear and fights creep, allowing it to operate in many metal applications.

*SP1* The unfilled base resin provides maximum physical strength elongation, toughness and the best electrical and thermal insulation.

*SP3* 15% by weight molybdenum disulphide added to provide lubrication for seals and bearings in vacuum or dry environments.

*SP21* 15% by weight graphite filler added to provide low wear and friction for bearings, thrust washers and dynamic seals.

*SP22* 40% by weight graphite filler added, this provides the same properties as SP21 for wear and friction plus improved dimensional stability. SP22 has the lowest coefficient of thermal expansion of all grades.

*SP211* 15% by weight graphite and 10% by weight PTFE fluorocarbon resin added. SP221 has the lowest coefficient of friction over a wide range of operating conditions. It also has the lowest wear rate of up to 300 °F.
